Security admin: Allow disabling token/perp init collateral (#482) 

This allows the security council to say "users can't create new borrows
against this token/perp anymore". In some emergency situations this can
help reduce risk exposure.

For example, if the price of a wrapped asset permanently depegs from
its underlying or there is a successful long-term attack on an oracle,
this (and reduce-only) would significantly reduce exploitability until
the DAO's decision for how to resolve the issue goes through.
